The ancients viewed heat as that related to fire. The ancient Egyptians in 3000 BC viewed heat as related to origin mythologies.
In the Western philosophical tradition, after much debate about the primal element among earlier pre-Socratic philosophers,Empedocles proposed a four-element theory, in which all substances derive from earth, water, air, and fire.

Conduction of heat

When one end of a solid rod is heated the atoms at that end vibrate – the more it is heated the more they vibrate. This vibration is passed on from one atom to the next and so the energy is transferred down the rod and this is conduction.

In metals there are also a lot of free electrons and these play a big part in the energy transfer.

Some materials conduct heat better than others.
Metals conduct heat better than non-metals
Thick specimens conduct heat better than thin ones
Liquids are poor conductors of heat
Air is a very bad conductor of heat
